Calculation of the capabilities of the railway infrastructure for the traffic of freight and empty wagons
Abstract
The results of a study of the dynamics of changes in the fleet of freight wagons, the impact of fleet redundancy on the efficiency and operability of the work of the railway network are presented. The purpose, scope, basic principles and assumptions, frequency of calculations and provisions of the Methodology for assessing the capabilities of the railway infrastructure for the traffic of freight and empty freight wagons are presented. The capabilities and needs of the infrastructure are determined by a hybrid model complex combining the results of simulation calculations with a network streaming model. Algorithms for calculating the interdependencies of functional capacity and the permissible level of traffic capacity utilization of railway network elements are presented. The procedure for assessing the permissible sizes of train and carriage traffic has been defined, taking into account traffic capacity losses due to failures of technical means and technological violations, as well as taking into account tasks for the departure of trains delayed in progress and for the normalization of the working fleet of wagons.
